Default Control Module Calibration?

Anyone have their PCM updated. It appears GM puts out updates that they send dealers to fix or calibrate the computer in cars?

An old thread states more about this at: http://forums.corvetteforum.com/zerothread?id=198930

Anyone have a list of these updates?

98 has 2 upgrades, one is non specific (09352201) and the other is for a cruise control problems with the active handling (09355171)

There are 10 different ones for 2001, including a couple of engine, 2 trans, a speedo calibration, diagnistic and a fuel system calibration.

I don't have VIN's for other years handy.

Found 2000. There are 9 calibrations available for 2000, similar to the 2001, but includes one that help prevent false spark-knock codes.
